No audio Asus C436FA (Cometlake) and C302 (Skylake)

Hello everybody again!
Me&wife are happy owners of 2 laptops with EndeavourOS on them for about 6 months :)), kiddos still on windols (on another 1 laptop), but they are just shorties :)))). Long storry in short - on both ower laptops we dont have audio from the speakers. Also no audio from the jacks. Via bluetooth we have super sound (external soundbox/headphones), but my question is did somebody managed to get sound from Cometlake and Skylake Chromebook laptops? On both laptops we have mr.chromebox BIOS, ex-Cromebooks, on both we run kernel 6.2.2-zen. I have heared that with the new 6.2 kernel, the intel AVS driver will be inplemented (or something:)) and will support alot of processors. Probably next time - with kernel 6.3/6.4 :wink: Thanx for your time reading this and every help will be appreciated!

The problem is sinds 6 months :slight_smile:

Could you check if the package sof-firmware is installed?

If not, please install it, reboot and check if it’s working.

sof-firmware is installed.

Can you post the output of lsmod | grep snd and lsmod | grep audio as in your inxi output the audio driver is n/a

Edit: and lsmod | grep sof as from an internet search I found that the kernel module for your audio device should be sof-audio-pci

Edit edit: if it’s not loaded you should be able to load it with sudo modprobe sof-audio-pci.

Thanx, man, but it seems not possible:
[r@r-helios ~]$ sudo modprobe sof-audio-pci
[sudo] password for r:
modprobe: FATAL: Module sof-audio-pci not found in directory /lib/modules/6.2.2-zen1-1-zen

[r@r-helios ~]$ lsmod | grep snd and lsmod | grep audio
grep: and: No such file or directory
grep: lsmod: No such file or directory

Oh, that were meant to be three different commands:
Command 1: lsmod | grep snd

Command 2:lsmod | grep audio

Command 3:lsmod | grep sof
